First considerations for your Finland sauna

• From a traditional Finnish point of view, a sauna is always a small wooden house, separated from the house. A location close to a lake or a river is ideal. So you can dive straight into the cooling water after going to the sauna. If this is not possible due to the spatial location, then you still do not have to do without your sauna.
• Another and easier option is to install a Finland sauna in the basement or in the attic of your house. When building your own, you should pay attention to a suitable material and the special structural conditions.

How to build your sauna

To the building In the Finland sauna, you use spruce planks. This type of wood is of high quality and, from a price point of view, a cheaper option compared to other types of wood. If you are building your own, install a special sauna heater with 380 volts.

1. You start by measuring the available space in your home. You then create an exact floor plan and work plan for your Finland sauna. Before starting construction, tile the floor of your future sauna. You want to be able to clean it quickly later.
2. To install the Finland sauna in a room, first pre-assemble a wall and place it in the room. The height of your sauna room is limited by the height of your respective door opening. Keep a distance of at least four centimeters from the wall for good ventilation.

3. First let the "sauna walls" be screwed shut using chipboard. In addition, attach the frame wood of about 3 to 4 centimeters to the wall edges. In doing so, it is necessary to indent the wooden pieces on the side and thus connect this wall with the rear or to screw the front walls.
4. Maintain a clearance upwards to the top squared timbers ceiling free, preferably in "wall thickness", so that the sauna lid will find its place here later.
5. Cut a door opening in the front wall, and cut more openings in the back wall. You should also have openings for small narrow air vents at the bottom of the walls provide. Attach additional transverse battens for further stabilization at the places for the bench seats.
6. After screwing the four sauna walls together, cover them inside with insulating material such as rock wool. The electrical line to the stove and lighting must also be provided. Finally, add a cladding. Strong aluminum foil, which serves as a vapor barrier and thus prevents moisture from penetrating the insulation material, is suitable for this.
7. You can clad the sauna interior with tongue and groove boards. Let these dry out really well in the heated room for two weeks and prevent the boards from getting out of joint as a result of the heat.

Finally, attach the already mentioned cover to your Finland sauna. You can do this tricky job by simply dismantling this lid into two parts. You can assemble the sauna ceiling in two steps. You connect the two halves from below with a wide wooden strip. Of course, you have prefabricated the cover halves beforehand and this complete with chipboard, squared timber and insulation material as well as the tongue and groove boards.

You design the interior according to your wishes

• Most important are the benches in the interior. For this you will find prefabricated built-in parts in specialist shops that you only have to assemble.
• The sauna heater also needs enough space and should be some distance from the wall and here with a thin, fire-retardant partition wall, which is once again thermally insulated from a safety point of view be. You screw this protective wall to the sauna wall. An electrician then professionally connects the furnace.

Alternatively, you have the option of buying a finished kit for your Finland sauna in the hardware store. But this is associated with higher costs than building it yourself.
